I recently went through and updated plugins (Cornerstone included) and my theme. I noticed that My portfolio pages are no longer loading. It just shows the animation for loading.
I tried remaking a portfolio page to test, starting with regular content then selecting the portfolio template layout and nothing happened which I found odd. It just remained the template from before.
The same thing happened when I try to select a different template on one of the already portfolio pages. I changed the template added content in cornerstone which showed in the viewer fine, but then when I refresh the page it remains the portfolio page with the constant loading.
This wasn’t happening before and honestly not sure when it started. I just noticed it when I was testing pages after the cornerstone and template update.
I also noticed that it was very similar to this post: Cornerstone update broke Portfolio
Thanks!
